gPECIFICATIfON forming part 6f Letters Patent No. 643,469, dated February 13, 1900; Application filed May 28, 1897. Serial No; 638,611. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL J. CLISE, of Midland, in the county of Allegany and State of Maryland, have invented certain new and useful Improvementsin Scrubbing-Machines;

4 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in scrubbing-machines; and its object is to provide a machine of this character with improved scrubbing mechanism whereby a fioor may be readily and expeditiously cleaned.

With this and other objects in view the invention consists in the novel constructions and combinations of parts hereinafter more fully described and specifically set forth in the appended claims.

. g r i .H Like numerals of referencedesignate corresponding parts throughout the several figures of the drawings. l

Referring now more particularly to the accompanying drawings, the numeral 1 designates the frame of the scrubbing-machine,- which comprises two side bars 2, a cross-bar 3, connecting the side bars 2 at the rear of the frame, and a metal plate or connectingbar 3 extending across at the front of the frame and connecting the front ends of the side bars. This bar is provided with two spaced upwardly-projecting loops or ofisets at and a handhold 5 between said offsets to afford means for raising the front end of the frame. The side bar 2 at the left-hand side of the machine is provided at the front and at the under side thereof with a cut-away space or recess 2*, through which the end of the scrubbing-brush frame projects, as will be hereinafter described.

Projecting upwardly from the side bars of the frame at the rear thereof are standards 6, provided at the upper ends thereof with notches for the reception of the bearing-blocks 7, each of the said blocks being formed with a vertical slot '7 for the passage of a confining-bolt 8, this construction of parts enabling the said bearing-blocks to be adjusted as desired. Braces 9 may be provided to assist in sustaining the bearing-standards, if desired. Connected with these standards at the upper end thereof is a handle-frame 10, consisting of two side arms or supports 11 and a transverse handle 12.

Connected with the side standards 2 on the inner side thereof and at the front of the frame are slide-rods 13, on which the brush-carrier frame is adapted to reciprocate. The brushframe comprises a metallic plate 14, to which a boardlo, carrying the brushes, is secured, said plate being provided with upwardly-projecting pins 16. The brush-board is provided with a lateral extension 15, which projects through the recess or cut-away space 2 at the under side of the side bar at the left-hand side of the frame a sufficient distance outward from said side bar to enable the machine to be operated for scrubbing the floor close to a side wall or other obstruction. On the metallic plate latis mounted a spider'loearing frame 17, formed with a central cross-bar or body portion 17 and a series of arms 17, radiating therefrom and provided with eyes or bearing projections 17, which engage the slide-rods 13. These arms are also provided adjacent said bearing projections with enlargements formed with openings 17, through which the pins 16 on the metallic brush-carrying plate project loosely. An adjustingscrew 18 operates in the threaded opening in the body portion 17 of the spider-bearing frame and also in the threaded socket in the metallic brush-carrying plate 14, acoil-spring 19-, surrounding said arm, being provided to maintain the parts in proper relation. By this construction it will be seen that the brush mechanism may be adjusted in a vertical plane as desired, and that, as the brushframe is not rigidly secured at any point, provision is made whereby one portion thereof may give or yield in a vertical plane to compensate for irregularities or undulations in the surface of the floor and to enable the brush mechanism to clear any obstruction which may be encountered without injury thereto, this being effected by the pin 16 moving loosely in the openings 17", the adjusting-screw 18 yielding slightly to permit of this movement.

The frame 1 is mounted at the rear upon rollers 20 and at the front upon rollers 21. The rollers 21 are mounted in bearing-brackets 22, and I have constructed and arranged the frame and bearing-brackets in such manner as to permit of the front of the frame being adjusted as desired to raise the brushcarrying frame either entirely out of contact with the floor or in contact therewith and to regulate the pressure of the brushes upon the floor independent of the adjusting-screw 18, heretofore described. To this end the brackets 22 slide vertically in openings in the front end of the side bars 2 and are connected at their upper ends by a cross-bar 23, which has position above the front ends of the side bars, as shown in Figs. 1 and 4, and is secured to the ends of the roller-brackets in any suitable manner. An oscillatory adjusting-shaft 24 is positioned between the cross connecting-bars 3 and 23 and is mounted in bearing projections 25, secured upon the former, and the end 24 of this shaft extends outward at one side of the frame, as shown. This oscillatory adjusting-shaft 24 carries two cam-disks 26, which occupy the loops or ofisets 4 of the connecting-bar 3 and are adapted to bear upon the bar 23. lVhen the shaft 24 is turned so as to force that portion of the periphery of the cam-disks which is farthest therefrom to bear upon the connecting-bar 23, the latter is forced down and carries with it the bearing-brackets, and the front end of the frame is forced up and the brush mechanism raised out of contact with the floor. In order to effect this operation, I have provided an adjusting-lever 27, pivotally mounted upon one of the braces 9 and having its lower end connected by means of a rod 28 with the laterally-projecting end 24" of the adjusting-shaft 24, as shown. This lever is provided with a spring-pressed pawl 29, adapted to engage the teeth of a segment-rack 30, so as to secure the parts and hold them in the position to which they have been adjusted. The connectingrod and the shaft may be limited in their throw or movement by stops 28" on the adjoining side bar 2 of the frame.

A drive-shaft 31 is mounted in the bearingblocks 7 of the standards 6 and carries a drivesprocket 32, said sprocket having a portion of its hub 33 formed with rack-teeth, with which a spring-pressed pawl 34 is adapted to engage to prevent the said shaft from being turned rearwardly, while readily permitting it to be revolved in the reverse direction, the pawl sliding over the teeth during this latter operation.

35 designates a crank-shaft mounted in bearings in the side bars 2 of the frame and I having its ends projecting exteriorly thereof. This shaft is provided at one end of its central crank portion 35 with a balance-wheel 36 and at the other side with a sprocket-wheel 37, which receives power from the drive-sprocket 32 by means of a chain 37. The adj ustability of the bearing-blocks 7 permits of the driveshaft and drive-sprocket being adjusted to take up any slack in the chain 37. The crank-shaft is also provided adjacent the sprocket 37 with a pinion 38, which meshes with a pinion 39, mounted on one end of an auxiliary drive-shaft 40, revolubly mounted in a bearing-bracket 41 and bearings in the side bar 2 at the right-hand side of the machine. The outer end of this auxiliary driveshaft is formed with a square head 42 and a threaded terminal 43, said square head being adapted to receive a clutch disk or collar 44, provided with an opening 45, and the threaded terminal end 43 being adapted to receive a nut 40, which is adapted to confine the said clutch-disk thereon. A sprocket-wheel 47 is loosely mounted on said shaft and is provided with a bolt or connecting-pin 48, operating in a slot 49 therein and adapted to be projected to engage the opening 45in the clutchdisk, and thereby rigidly connect the said sprocket-wheel with the shaft and cause it to be revolved therewith. The slot 49 is provided with two lateral offsets 49 49", and the bolt is formed with a pin 48, which is adapted to fit in either one'of said offsets. By means of said pin the bolt 48 may be thrown into and out of engagement with the clutch-disk 44 and held in said position. When the pin occupies the lateral offset 49, the bolt is projected and rigidly connects the sprocket with the clutch-disk; but when occupying the offset 49 it disconnects the sprocket from said disk and leaves the said sprocket free, so that the shaft may be turned independently thereof.

The brush mechanism is adapted to be reciprocated by means of the crank shaft through suitable connections therewith. In

the present instance I have provided a connecting-rod 50, pivoted at one end between two ears 51 on the spider-bearing frame 17 and formed at its other end with an engaging hook 52, adapted to engage the offset or crank portion 35 of the crank-shaft 35 and provided with a socket or opening 53 for the reception of a tongue 54 on the sliding latch or keeper bar 55, said bar being provided with a clamping-screw 56 to engage the shaft and retain the connecting-bar in position thereon.

This latch-bar is mounted to slide on the connecting-bar by means of confining-screws 57, projecting through slots 58 therein and entering threaded openings in the connectingbar, as clearly shown in Fig. 6. By this mode of connection the connecting-bar may be quickly and conveniently thrown into and out of engagement with the crank shaft. When the machineis not in operation,the connecting-bar 50 is adapted to be thrown forward and locked in position by means of the latch mechanism just described upon the handhold 5 of the connecting-bar 3 at the front of the frame. By the mechanism hereinbefore described it will be seen that by operating the drive-shaft 31 through the medium of its crank-handle the brush mechanism may be reciprocated rapidly on the sliderods 13, so as to quickly and effectively scrub the floor.

In the operation of the device it will be understood that the floor is first watered and soaped as desired independent of the machine, although I may provide the machine with a water-reservoir and suitable means for employing soap or any other desired cleansing agent or compound.

The scrubbing-machine is also provided with drying mechanism of novel construction, adapted to dry the floor after the scrubbing operation has been effected. To this end I have provided a three-sided drying-frame 59, the side arms 60 of which have their inner ends adjustably mounted in bearing-brackets 61, secured upon the outer projecting end of the crank-shaft 35 and retained thereon by a bolt-and-nut connection 62. This frame is provided at the rear with a transverse supporting bar or plate 63, depending therefrom and suitably connected therewith and adapted to receive a receptacle 64, in which the water taken up from the floor is adapted to be received. This receptacle is adapted to be slid into and out of the frame and supported by the said plate or bar 63. In order to hold the receptacle in position, I have provided the rear cross-bar 60 of the frame with a springactuated detent or latch 65. Mounted in this frame upon a shaft 66 is a drying-roller 67, which projects transversely of the frame, at the rear thereof, and has one end extended beyond the line of the side bar 2 of the frame at the left-hand side of-fthe machinein line with the lateral extremity 15 of the scrubhing-brush. This drying-roller is of novel construction and consists of a roller proper,

66 of wood or other suitable hard material to give body and strength thereto. Around this roller is a covering or sheathing 68, of sheet-rubber or other suitable waterproof material, and covering this rubber a layer of absorbent cotton or other suitable material of this character 69, which is adapted to absorb moisture and is yielding or compressible to permit the roller to give or yield when encountering an obstruction or inequalities or undulations of surface in thefloor without affecting the other portions thereof. An outer layer of canvas or other suitable material which possesses a certain amount of rigidity, with sufficient elasticity, incloses the absorbent material and is provided around the circumference thereof at regular intervals with a series of flaps 71. These flaps form between them pockets to receive and confine the water taken up from the surface of the floor and are formed by lapping the canvas or other material employed and uniting said lapped portions by stitching 72, as illustrated in Fig. 13. These flaps project tangentially in the same direction and are adapted to take or scoop up the water from the surface of the floor and carry it around until the receptacle 64 is reached, whereupon the water will begin to run out of the said pockets formed by the flaps and into the said receptacle.

In order to insure that all the water taken up by the roller and absorbed by the absorbent material 69 may be discharged from the roller, I have provided mechanism adapted to bind against the periphery of the said roller and express the water therefrom and conduct it to the said receptacle 64:. To this end the drier-frame is provided with two segment-shaped arms 73, one arranged at each side of the frame, said arms having their ends adjoining the scrubbing-frame pivoted at 74C to the side arm 60 of the drier-frame and provided at said end with a lip or projection 75. The arms are connected by transverse connecting-rods 76. Pivoted to the rear ends of these rods is a transversely-arranged blade or bar 77, provided with a beveled edge 78, adapted to bear upon the periphery of the roller and force the water out of the pockets formed by the flaps 71 and also express the water which may have been absorbed by the absorbent material 60. This blade or bar is arranged at an inclination above the mouth or opening 64 of the receptacle 64, and the water from the roller flows down upon the said bar or blade and enters the said receptacle, which latter may be removed when full and emptied. In order to cause the blade 77 to bear firmly against the roller, I have provided a lever 73, Fig. 7, pivoted to the arms 60 by a pivot-bolt S0 and having two angularlyarranged ends, one of which bears against the under side of said lip-projection 75 of the segment-arms 73, and is adapted to force the said lips upward, so as to cause the trans verse blade or bar to bear firmly against the periphery of the roller. An adj Listing-screw 81, operating in a bearing-bracket 82, is adapted to bear against the opposite end of the adj usting-lever to accomplish this result. To effect a further adjustment of the pivoted bar or blade independent of the segmentarms 73, I have provided the inner end of each segment-arm '73 with an adjusting-piece S3, pivoted thereto by a pivot-bolt 84 and having a loop-shaped end 85 secured to the lower end of the clearing-blade 77 and a rearwardly-projecting bearing-lip 86, (see Figs. 4 and 10,) forming the opposite end of the adjusting-piece, arranged at the other side of the blade. Adjusting-screws 87, operating in bar projections 88, are adapted to bear on said lips and cause the said loop-shaped ends to be forced inwardly, so as to press the cleaoing-blade against the roller. By this means, when the limit of adjustment of the segment-arms has been reached the clearing-blade may be further adjusted independently thereof to bear with any desired degree of pressure against the periphery of the driveroller.

In order to lift the drying-roller and its frame out of contact with the floor when the machine is not in use and is being transported from one place to another, I have provided a shaft 89, having hearings in the two side arms 11 of the handle-frame and extending parallel with the handle 12. This shaft carries a pawl 90 and two forwardly-projecting arms 91, which are connected with the pivoted arm of the drien-frame by connecting-rods 92. A segment-rack 93 is pivoted to the inner side of one of the side arms 11 of the handle-frame and is provided at its lower end with a laterally-projecting lip 94, having a threaded opening for the reception of an adjusting-screw 95, operating in said side arm, as shown. By this construction it will be seen that the position of the segment-rack may be varied so as to project the teeth thereon higher or lower, accordingly as it is desired to adjust the drying-roller and its frame.

The shaft of the drying-roller is provided with a sprocket-wheel 96, which receives motion from an auxiliary drive-shaft 40 by means of a chain 97 engaging the sprocket 47 on said auxiliary shaft. By means of the clutch connection, hereinbefore described, of this sprocket 47 it will be seen that the dryingroller may be thrown into and out of action at any time by releasing the bolt 48 from the clutch-disk 44:, whereupon the sprocket -L7 Will be disengaged from the auxiliary shaft and no motion will be imparted to the shaft of the drive-roller for revolving the latter.

The operation is as follows: The machine is pushed across the surface of the floor and the drive-shaft 31 revolved to reciprocate the brush-carrier frame, which operation is continued until the entire surface of the floor has been scrubbed. The drying-roller following the brush mechanism-takes or scoops up all the water and dirt and discharges the same,

by means of the mechanism just described, into the tray or receptacle 64, which latter may be removed and emptied when filled.

I do not desire to limit myself to the specific construction and relation of parts hereinbefore described, but reserve to myself the right to make such changes and modifications as fairly fall within the spirit and scope of my invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is
